Here we answer the question: "What two numbers multiply to 780 and add up to -199?"

The answer to your question is:

-195 and -4


Below we illustrate and prove that -195 and -4 multiply to 780 and add up to -199:

-195 × -4 = 780
-195 + -4 = -199

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x2 - 199x + 780 = 0

If so, the solution to factor the quadratic equation above is:

(x - 195 ) (x - 4)

To summarize, since -195 and -4 multiply to 780 and add up -199, you know that the following is true:

x2 - 199x + 780 = (x - 195 ) (x - 4)
